Abstract
The water beam with slider is an improvement relating to water beam slider production method in industrial heater. The present invention provides a water beam with slider saving expensive metal materials. The invention hot melts the high temperature materials and low temperature materials into one unit using casting mean; it adds high temperature materials (or low temperature materials) in the casting cavity, then injects low temperature liquid (or high temperature liquid) under the state of metal liquid or solidified high temperature and alloying, getting the slider; at last putting the slider on the water beam.
Description
Technical field:
The present invention relates to the improvement of water beam slide block production method in the industrial heating furnace.
Background technology:
Slide block on the water beam in the heating furnace is under the furnace high-temperature condition, in order to support the slip of heated steel material.Existing slide block roughly is divided into three kinds: a kind of is the slide block (see figure 3) of single material, because of adopting a large amount of expensive high temperature alloys, and has increased manufacturing, the maintenance cost of heating furnace; And its inner cooling velocity is slower in slide block casting solidification process, and the metal grain of crystallization is thick, and the product combination property is poor; Another kind is split type slide block (see figure 4), and the high performance heat resistant high temperature alloy is adopted on top, and common high temperature alloy is adopted in the bottom; But because be split type, stability in use difference and service life are short, and less being used; Be laser melting coating Co60 slide block (see figure 5) again, then have the problem that clad is thin, the life-span is short.
Summary of the invention:
The present invention is exactly at the problems referred to above, but a kind of water beam slide block of conserve expensive metal material is provided.
According to the work characteristics of slide block, can be divided into high-temperature region, top, bottom low-temperature space.The high-temperature region, top needs to adopt high heat resisting temperature high-temperature alloy material, and low-temperature space can adopt the low heat resisting temperature high-temperature alloy material of relatively-high temperature district material.
The present invention adopts following technical scheme: the present invention is exactly the monomer slide block that adopts forging type that high-temperature region material and low-temperature space material hot melt are integrated; Promptly in casting mold cavity, add high-temperature region material (or low-temperature space material),, inject low-temperature space molten metal (or high-temperature region molten metal) fusion back at once at metal liquid or under the condition of high temperature after solidifying; Then slide block is placed Shui Liangshang.
Beneficial effect of the present invention:
In the hot environment of slide block in heating furnace body, and the slip of top support heated steel, require material that better heat resistant and wear resistant performance is arranged; The slide block lower part directly contacts cooling water pipe and the heat-resistant coating layer is arranged, and its material requirements is than the low relatively heat proof material of top high-temperature heat-resistance material, and the satisfied needs that support get final product; Production method of the present invention can fully satisfy this working condition requirement.The use amount that this production method makes the slide block lower part reduce expensive metal is 30%-70%; And reduction device fabrication cost and maintenance cost (Slipper can be saved 40%-50%); Cooling condition was good around the fusion of slide block middle part excessively was with, and metal grain is tiny, the combination property height, and the antifatigue degree improves 15%-20%; The slide block long service life.In addition, this technological principle is simple, and relevant device is few, is convenient to operation.

The specific embodiment:
Have clad 1 outside the water beam 4 of the present invention, slide block 3 passes clad 1 and contacts with water beam 4.
Embodiment:
One, 1, adopt investment precision casting technology to make silicasol case 8;
2, at roasting kiln roasting shell 8, and 700 ℃-1150 ℃ insulations of high temperature 25-50 minute;
After shell 8 took out from roaster, dead head 7 parts coated insulation with flame-proof thermal insulation materials such as alumina silicate felts;
3, with 1500 ℃-1600 ℃, preferably 1580 ℃ Co50 high temperature alloy liquid injects the good high temperature shell 8 of roasting;
4, treat that high temperature alloy liquid liquid level solidifies after, under the condition of high temperature, inject 1620 ℃-2000 ℃ of pouring temperatures at once, preferably 1680 ℃ Cr25Ni20 high temperature alloy liquid; Make high-temperature region, top 6 Hes
Two kinds of material C o50, Cr25Ni20 of lower part low-temperature space 5 fuse in contact portion;
5, after high temperature alloy liquid solidifies cooling fully, clean shell 8, cut away dead head 7 promptly.
Two, high-temperature region, top 6 adopts material to be preferably: Cr25Ni20, Cr28Ni48, Co20, Co50, Co60;
Low-temperature space 5 materials in lower part are preferably Cr25Ni20, also can adopt Cr18Ni9 or Cr28Ni48 to arrange in pairs or groups with high-temperature region, top 6 materials.
Make slide block 3 with high-temperature region, top 6 materials with the collocation of low-temperature space 5 materials, be sequentially arranged on the water beam 4; Be fit to the operating mode that steel material 2 is heated up gradually in the heating furnace, saved expensive high temperature alloy preferably.
